Based on the needs of many netizens, I have dedicated my online chat on this simulated OICQ! 1. you must register for login. you do not need to ask if you save the following field names in the database userinfo. this is the username used for login. you must use the unique Password to log on to the NickName user NickName, that is, the displayed SyntaxHighlighter. based on the needs of many netizens, I have dedicated my online chat on this simulated OICQ!

1. the user must register for login and save the following fields in the database userinfo:
No need to ask, this is the login user Name, must be unique
Password login Password
NickName: The NickName of the user, that is, the name displayed.
Face stores the user Avatar number, such as 01, representing/images/face/01.gif Avatar file
OnlineStatus indicates whether the user is online. it is set to 1 when the user logs in.
CurrentDate the last time the user accesses/updates, used to determine whether the user is online

The structure of the chat record forumtalk is
Create table forumtalk (
Id int (11) not null auto_increment,
Sender varchar (20) not null,
Receiver varchar (20) not null,
Date int (11) DEFAULT 0 not null,
Readsign tinyint (4) DEFAULT 0 not null,
Body varchar (200) not null,
Prima (the most complete virtual host Management System) ry key (id ),
UNIQUE id_2 (id ),
KEY id (id)
);
The sender is the sender's Name.
The receiver is the receiver's Name.

2. display the avatar of an online user
$ Onlineresult = MySQL (the best combination with PHP) _ query ("select Name, NickName, Face, EnterTimes from userinfo where OnlineStatus = 1 and CurrentDate> ". (date ("U")-120 ));
$ Onlinenumber = MySQL (the best combination with PHP) _ num_rows ($ onlineresult );
Echo "Welcome, a total of:". $ onlinenumber. "a friend online, send a short message according to the Avatar :";
For ($ I = 0; $ I <$ onlinenumber; $ I ++)
{
If (! $ Onlineuser = MySQL (the best combination with PHP) _ fetch_array ($ onlineresult) break;
Echo "(as the mainstream development language )? Talkto = ". $ onlineuser [Name]. ",". $ onlineuser [Name]. ", width = 300, height = 250)> if ($ name = $ onlineuser [Name]) echo" border = 1 ";
Echo "title = code:". $ onlineuser [Name]. "NickName:". $ onlineuser [NickName]. "access:". $ onlineuser [EnterTimes]. "> ";
}
?>
